Kavanaugh has adamantly denied it. Why would you recommend a strategy for dealing with it that is based on the presumption that it DID happen?
Now that she is no longer anonymous, has supporting docs from 2012, and passed a lie detector test, most people will believe that something happened. There was a party, Kavanaugh was there, they were drunk. Anything more than that, deny the details, deny the relevance. If you deny the entire thing, one other witness saying Kavanaugh was at the party will kill the nomination.
Has Kavanaugh said anything today since the accuser came forward?
